Essays on Electrical engineering

In isolation applications where one needs to pass signals in presence of transient or continuous high voltages, reject extreme noise, and break ground loops, optical (optocouplers) and magnetic (pulse transformers) coupling isolation are often used. However pulse transformers are much more difficult to design with relative to optocouplers. When dealing with pulse transformers, the load…

Photovoltaic cells are solid state devices that convert light directly into electricity. Photovoltaic literally means “light electricity.” These devices can be commonly found providing power for small scale devices such as calculators, watches, and small radios. However, they are not limited to small scale systems. They are also used to power satellites, communications equipment, houses…

Secondarily, its thickness allows for wear over the life of the clutch. However, that wear results from a fundamental drawback of diabetics design. Since the armature is thick and massive, it has a high inertia, and all of its originally stationary mass must be “spun up” to match the rapidly rotating pulley and friction disk…

The duties of the section involve reagent storage and mixing, determining the dosage of reagents, ample preparation, metallurgical accounting and dispatch of the concentrate for further processing. Production – duties include receiving ore, ore milling, monitoring flotation cells, concentrate handling and tailings handling. The process at the concentrator is semi- automated and is monitored by…

An electric generator is fundamentally an electric motor working backwards. An electric motor converts electrical energy into mechanical energy. and an electric generator converts mechanical energy into electrical energy. An electric generator looks about indistinguishable to an electric motor. Each consists of a cringle that is able to revolve in a magnetic field. The electric…

Besides connecting the arioso network segments, the backbone may have its own devices that can be accessed by other network segments Metropolitan area network (MAN): MAN spans a city and is Often used to connect remote BANS. MAN in some cases can be considered a citywide BAN and as the geographic distances they cover have…

Wireless signals have pros and cons that influence their commercial use and present day application. However, no matter the progress made with wireless signal frequencies they are always subject to interference from technologies limiting their effeteness. Microwave Signals Microwave signals transmit using electromagnetic energy. Microwave signals are used commonly in long distance telephone telecommunications, cellular…

In statistical signal processing, the sampling times are most often taken to be equally spaced. However, several applications need that non-uniform sampling is important. The major work on nonuniform sampling is for when the sampling times can be specified, and the signal processing community lacks tools to deal with standard issues like identification and decimation…

Abstract Electronic pills, smart capsules or miniaturized microsystems swallowed by human beings or animals for various biomedical and diagnostic applications are growing rapidly in the last years. This paper searched out the important existing electronic pills in the market and prototypes in research centers. Further objective of this research is to develop a technology platform…

SAN implementation over Gigabit Ethernet A Storage Area Network is virtualized storage. A storage area network (SAN) is a dedicated, centrally managed, secure information infrastructure, which enables any-to-any interconnection of servers and storage systems. A SAN can be configured to provide a nearly infinite pool of storage that you can grow and move between servers…
